| Conversion means you still have the NA rear diff which will fall way short of 200mph, aside from all your other power parts. With a TT running X amount of Boost ( way over stock ) and a 7200rpm rev- limit ( at least ) on 275 x 35 x 18 tires max speed is around 197mph before you run out of gears/rpms. NA 4.10 gears will take you down to a 178mph max to redline
 STAGE V++++ Going to XV+ and beyond :) Yellow Z STAGE II Going to XI+ |
